Atmel recently announced that it has signed a definitive agreement to acquire Ozmo Co., Ltd. The latter is an ultra-low-power Wi-Fi solution provider. This acquisition will expand Atmel ’s wireless product line and further enhance the development and design capabilities of smart, connected and Internet of Things devices.
Ozmo brings innovative "Wi-Fi Direct" authentication technology to Atmel's wireless product portfolio, which will accelerate seamless communication and connectivity of wireless personal area networks (WPANs). This product is specially designed for consumer electronics products, has a smaller package and longer battery life, and is widely used in gaming peripherals, HD audio speakers, portable audio headphones, digital thermostats, household appliances and remote controls. , Ozmo ’s Wi-Fi products and technologies provide ultra-low power, low-cost solutions for the connection platform between fixed and mobile devices.
"This acquisition accelerates Atmel's 'Internet of Things program' and enables us to provide more complete solutions and products," said Steve Laub, President and CEO of Atmel, "as a leader in Wi-Fi Direct technology , Ozmo ’s solutions are widely distributed in this rapidly growing market. We will continue to support Ozmo ’s existing customers and expand the sales of Wi-Fi Direct products through Atmel ’s global sales channels and marketing network. We will integrate Ozmo ’s IP and Atmel microcontrollers have introduced more attractive products. "
According to market research data, the global wireless peripheral market is expected to reach one billion units in 2015, and Wi-Fi Direct is the fastest growing part of it, with a compound annual growth rate of more than 100% by 2015. Atmel expects the transaction to be completed by the end of this year and is expected to achieve profitability by 2014.
Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material
Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
